    • Decision making is a dynamic process. Alternatives compete over time, and this competition plays out in sensorimotor processes. This is true not just for perceptual decisions or simple categorisation tasks, but also for moral decisions, which are the outcome of a complex interplay of intuition, emotion and reasoning. In this experiment, we first establish a descriptive and causal link between gaze and moral judgement. We then use eye movements to track the time course of participants’ moral decisions and show that by interrupting their decision process based on their gaze position, we are able to influence what they decide. We interpret this as evidence for a dynamical systems view of decision making and argue that our results provide new insights into how judgements are reached and constructed in our embodied minds.

    • If our choices make us who we are, then what does that mean when these choices are made in the human-machine interface? Developing a clear understanding of how human decision making is influenced by automated systems in the environment is critical because, as human-machine interfaces and assistive robotics become even more ubiquitous in everyday life, many daily decisions will be an emergent result of the interactions between the human and the machine – not stemming solely from the human. For example, choices can be influenced by the relative locations and motor costs of the response options, as well as by the timing of the response prompts. In drift diffusion model simulations of response-prompt timing manipulations, we find that it is only relatively equibiased choices that will be successfully influenced by this kind of perturbation. However, with drift diffusion model simulations of motor cost manipulations, we find that even relatively biased choices can still show some influence of the perturbation. We report the results of a two-alternative forced-choice experiment with a computer mouse modified to have a subtle velocity bias in a pre-determined direction for each trial, inducing an increased motor cost to move the cursor away from the pre-designated target direction. With queries that have each been normed in advance to be equibiased in people’s preferences, the participant will often begin their mouse movement before their cognitive choice has been finalized, and the directional bias in the mouse velocity exerts a small but significant influence on their final choice. With queries that are not equibiased, a similar influence is observed. By exploring the synergies that are developed between humans and machines and tracking their temporal dynamics, this work aims to provide insight into our evolving decisions.
